Hey Tim,
You have mentioned twice that you up convert to a high quality 10 bit format for editing in Premier. I would love to know how that is done. My understanding is that the MXF P2 format is limited to 8 bit no matter what the camera can see. Any up converting of MXF media is surely going to be based on software assumption as the bandwidth is lost as it goes to the card. I know up-resing is effective in a limited fuzzy way with clever interpolation algorithms. I would love to know if you have done a comparative chrome-key between the native 8 bit footage and up-converted 10 bit equivalent. Is it an avenue worth pursuing or is it as I suspect a lot of time & work for a fuzzy gain?
I work in Premier Pro & Final Cut Pro. Though FCP is an amazing editor (and compositor) it does not have seamless integration with MXF as it takes time to unpack the files into QuickTime (+-real time in HD 720 on the 2.8 GHz Mac Pro) and does not support all shooting formats including in my opinion the very useful 720P50! Go figure. I looked at the Edius Broadcast demo today which is lightning fast but of course requires the additional cost of a Canopus card for any sort of quality output. These two piece of software are a secondary focus & have been developed to sell computers and cards respectively so when a company like Adobe whose primary focus is software falls so short of the mark with CS3 regarding format compatibility (no Panasonic cameras even listed in there compatibility chart) & perhaps even as a comparable edit package, one has to ask whether the moneys not in hardware. They need to make a bold statement to get my, and I am sure many others upgrade money. We also have VT Edit (Video Toaster) which makes MXF claims but is a real dog with MXF and not really a workable solution. In conclusion my extremely cheap Panasonic HPX 500 camera has turned into a extremely expensive and frustrating post production nightmare. Research, research, research!
Regards Matthew
PS: I withhold my opinion on up-resing from 720P 50 to 1080i as interlaced footage is inherently half the res to start with.
